To determine: The important resonance forms for the given compound; the major and minor contributors in the resonating structures; if they have the same energy and any important missing resonance form.
Interpretation: The important resonance forms for the given compound are to be stated; the major and minor contributors in the resonating structures are to be indicated; whether they have same energy is to be stated and any important missing resonating form is to be stated.
Concept introduction: Resonance is the process in which a molecule gets different structures to define its bonding within the molecule. Such molecules cannot be represented in single Lewis structures. Resonating structures of such molecules are called contributing structures. In the process of resonance shifting of lone pairs occur with the bonds and other lone pairs.
The major contributors are those resonating structures in which almost all the atoms have filled octet.
The minor contributors are those resonating structures in which atoms do not have complete octet and electronegative atom carries positive charge and vice-versa.

- I am having trouble on part c. It wants me to draw the resonance structure, but in mastering chem there’s no arrows available for some reason . Is there a way to draw it without the arrows and still be resonancearrow_forwardThe two molecules in the pictrue behave very differently in reactions. Though they are both neutral, it is possible to draw resonance structures to illustrate which atoms will have partial charges. In one of the molecules, a carbon of the double bond is partially positive while in the other it is partially negative. 1. Draw one resonance structure for each molecule below with only one positive and one negative charge in the left box. In the box to the right draw out the original structure with its partial charges, which can be determined from the resonance structures.arrow_forwardFor each proposed set of resonance structures: a. (E) Add curved arrows (starting from left) to show how each successive r.s. was generated. b. Cross out any resonance structures that are NOT important, and explain your reasoning.arrow_forward
- Pairs of unshared electrons can be pushed. One Lewis structure for the methoxy-methyl cation is . The structure contains a pair of pushable electrons, namely, the unshared electrons on the atom. The structure also contains a positively charged atom that can act as a . A second resonance structure can be generated by pushing the unshared electrons to the receptor. Thus, It is not possible to push electrons toward the other carbon, because it is not a receptor. If you tried to push electrons to this carbon, you would generate a pentavalent carbon, which is not possible.arrow_forwardWhich of the following shows correct arrow placement that represents significant resonance for the given molecule? None of the choices given represent significant resonance.
